If you don't want a full cup of this dressing, halve the recipe...you might need to use an immersion blender to get all of the ingredients well incorporated. 

Alternately, make a full batch and freeze the excess.

You'll get a more even distribution of the dressing if you toss the salad greens—whatever kind you're using—in the dressing before plating. 

For a sturdy green like kale, massage the dressing into the leaves with your hands.

Keep in mind that a little goes a long way! Nobody likes an overdressed salad.
